"Naru-chan won't you come out and play with me?"

Childish giggles filled the air, the blue eyes boy was excited, his dear ane, his sister was back from a mission after so long.

"Of course!"

Rize kamishiro was an average jonin with no noticable talents, only being recognised as a respectable asset for the village. She was also one of the few people that wouldn't shun Naruto because of his burden, no she had been blunt telling the boy of what he held inside of him and showing him affection to keep him sane.

Disregarding the thirds law had been risky, but the child had a sense of fierce loyalty towards her and would never go against her.

How foolish he had been, to trust her.

"Come on Naruto, its been so long lets go inside you can paint! I'll show a pretty shade of red you haven't seen yet!"

"Really! Wait, let me get up!"

He felt sick to his stomach thinking of that cursed day, his blind faith in her, that she would never deceive him had caused him to become the monster that he was today.

"Onee-chan, w-what happened to you?"

To his naive eyes, all he saw was blood red tentacles protuding from his dear sisters back, an emotion he couldn't recognise distorting her features.

But they were no tentacles, no it was a rinkaku, one that she would use to rip him apart.

"Did being alone for so long teach you nothing Naruto-kun?"

Her laughter echoed through out the house, the tempreture droping leaving him shivering.

"W-what do you mean?"

But Naruto didn't receive an answer, instead Rize leaped at him, his short legs causing him to stumble to the ground. Beside him the wall crumbled as her rinkaku impaled his shoulder holdind himself into place.

"I always wondered what it would taste like to eat a demon."

A broken whimper escaped from his throat, she promised, she had promised him.

Red chakra escaped from the seal on his stomach healing some of his wounds, a deep voice that didn't belong to the child left his mouth.

"You will not kill ME."

The same red chakra lashed out violently forming red tails, in anger the kyuubi took control killing Rize. But it wouldn't be enough, his vessels body could only take so much, and with the major wounds still bleeding paired with the demonic chakra he would die soon taking the demon with him.

But Naruto hadn't died, with the Hokage and the anbu being alerted of the nine tails chakra they had rushed to the source and were met with a gruesome sight.

Rize Kamishiro was dead slumped over Naruto's body, with the boy himself not fairing well, although still breathing, his pulse was still faint. He would need medical attention immediately.

Naruto wished that he hadn't been saved that day.

Having lost so much blood and taken heavy damage, he had to rely on having multiple organs replaced.

Replaced with hers.

And it was why he found himself they way he was today,- single blood red kakugan,feeding of victims from the TI department to stay alive, so that he could feed his sickening desires without harming anybody.

He was the monster they all claimed him to be.
